Definitions
- the present invention relates to a closure for a container, and in particular, a snap resealing overcap for a container.
- Containers such as those for various food products, such as coffee, often comprise a sealed metal container.
- Traditionally one would gain access to the contents of the container by using a can opener to remove the lid or top of the container.
- a separate plastic overcap has traditionally been attached to the container around the chime to cover the opening once the original lid or top had been removed.
- the overcap is a simple annular disc with a vertical skirt extending down and engaging a corresponding exterior surface of the chime of the container.
- containers include replacing a metal container with a plastic container, such as a container formed from polyethylene or polypropylene.
- plastic containers typically include a peelable foil membrane over the opening as described above.
- U.S. Pat. No. 3,380,610 discloses a flexible closure for the neck of a container in which an annular sealing member of the closure hingedly connects an inner portion thereof to the rest of closure.
- the sealing member includes a portion which extends radially outward from the inner portion to snugly engage an inside surface of the container neck.
- U.S. Patent Application Publication No. 2003/0010787 discloses an overcap having a dome portion which can be used to accommodate pressure build-up in the container and subsequently to “burp” the container during use of the overcap, although the method of “burping” is not disclosed.
- the overcap seals along two lines of the container, namely along an inward extending flange of the container and, with its skirt, along an outer rim of the container.
- the present invention concerns a new and improved overcap for a container.
- the overcap includes a dome which is in an upward convex position, as viewed looking down from above, as originally applied to the container and upon a downward force applied to the dome is displaced inwardly to transform the dome to an upward concave position.
- the overcap snappingly engages with the container during the downward movement to produce an audible indication that the overcap has tightly engaged with the container.
- this overcap expels air present inside the container during such downward movement.
- the expelling air produces an audible “swoosh” sound to indicate to consumers that air is expelled, a good seal is formed, and freshness is “sealed-in.”
- a second advantageous feature of this overcap is that it produces a better, tighter seal when the overcap is affixed to a container and transformed to its concave position.
- the present invention in one form thereof, relates to a closure individually or in combination with a container, comprising an overcap having a skirt with an inwardly facing surface engageable with the exterior of a container and an invertible dome which is transformable between a convex position and a concave position.
- the dome expels air from inside the container when transformed from the convex position to the concave position, and the dome maintains its concave position after transformation.
- the overcap preferably produces an audible noise upon inversion of the overcap.
- the inwardly facing surface of the overcap is engageable with the exterior of a container along at least two lines, and advantageously, at along at least three lines.
- the overcap forms a tighter seal with the container when in the concave position as compared with the convex position.
- the overcap is transformed from the convex position to the concave position in a single action by applying force to the invertible dome with one hand.
- the present invention in one form thereof, relates to a closure, individually or in combination with a container in which the closure includes an overcap having an outer wall with an inwardly facing surface which engages with the exterior of the container and an inner wall with an outwardly facing surface having a plurality of pairs of convex projections extending radially outwardly towards the outer wall.
- the convex projections include an upper projection and a lower projection. Each of the pair of projections is adapted to permit a flange of the container extending radially inwardly from the periphery of the container to be disposed between the upper projections and the lower projections.
- the overcap has an invertible dome which is transformable between a convex position and a concave position.
- a V-shaped portion is disposed between an outer ring projection and an inner ring projection and the V-shaped portion forms a hinge between the outer ring projection and the inner ring projection;
- the V-shaped portion includes a bottom bridge which engages a top surface of the flange of the container; and (3) a plurality of vent channels are located on an inward side of the dome and extend radially to a location between each pair of upper and lower projections.
- the present invention in yet another form thereof, relates to a closure individually or in combination with a container in which the closure comprises an overcap having an outer ring projection and an inner ring projection.
- the outer ring projection engages the exterior of the container and the inner ring projection engages the flange of the container which extends radially inwardly from the outer periphery of the container towards a top opening of the container.
- the overcap has an invertible dome which is transformable between a convex position and a concave position.
- a V-shaped portion between the outer ring projection and the inner ring projection forms a hinge between the outer ring projection and the inner ring projection.
- the present invention in another form thereof, relates to a closure individually or in combination with a container in which the closure comprises a snap overcap having an inwardly facing surface engageable with the exterior of a container and an invertible dome which is transformable between a convex position and a concave position.
- the dome maintains its concave position after transformation.
- the overcap preferably produces an audible indication that the overcap is securely affixed to the container.
- the present invention in yet another form thereof, relates to a closure individually or in combination with a container in which the closure includes an overcap having an outer ring projection and an inner ring projection and a plurality of vent channels located along an inward side of the overcap and extending radially from a center portion of the overcap to the inner ring projection.
- the present invention in another form thereof, relates to a closure individually or in combination with a container in which the closure comprises an overcap having an outer ring projection and an inner ring projection for placement over an opening of a first container.
- the outer ring projection has a circumference shaped to engage a bottom rim of a second container to thereby permit the first container to be stacked on the second container.
- the present invention in yet another form thereof, relates to a package with an overcap comprising a container with a bottom rim and an overcap having an outer ring projection and an inner ring projection for placement over an opening in a first container.
- the outer ring projection has a circumference to engage with a bottom rim of the second container.
- the present invention in another form thereof, relates to a package with an overcap comprising a container having interior sides, a bottom, and an opening at the top; and an overcap having a skirt with an inwardly facing surface engageable with the exterior of the container, the overcap having an invertible dome which is transformable between an upward convex position and a concave position, wherein the overcap forms a tighter seal with the container when in the concave position as compared with the convex position.

- the container could be made of metal or any other suitable material including plastics such as polyethylene and polypropylene, and can have any shape or size appropriate to package the desired product.
- the top of the container 50 is sealed by a flexible peel-off membrane 54 formed of a flexible foil material, which membrane is hermetically sealed around its periphery to a ledge in the form of flange 53 which is integral with the container 50 .
- Container 50 includes sides 51 , a chime 52 and the flange 53 which defines a top opening in the container when the peel-off membrane 54 has been removed.
- the easy peel-off membrane 54 has a pull tab 55 .
- the overcap 10 is composed of resilient material such as polypropylene or other suitable material. Referring to FIGS. 1-4 and 6 , but in particular to FIGS. 3 and 4 , it attaches at two radially spaced peripheral locations of the container 50 to be disposed over the membrane 54 and to seal the opening of the container 50 after membrane 54 has been removed.
- One attachment is where outer ring projection 20 resiliently engages an exterior surface 52 a of chime 52 along inwardly facing surface 22 of outer wall 21 .
- the other attachment is where an inner ring projection 30 contacts the flange 53 at flange surface 53 a . As best shown in FIG.
- an inner wall 31 has an inwardly facing wall surface 32 with a series of pairs of radially upward convex projections in the form of upper projections 34 and lower projections 36 .
- the upper projections 34 and lower projections 36 straddle flange 53 with inwardly facing wall surface 32 adjacent flange surface 53 a.
- V-shaped portion 15 Between outer ring projection 20 and inner ring projection 30 is a V-shaped portion 15 with bottom surface 16 which abuts or is adjacent to flange surface 53 c when overcap 10 is affixed to container 50 .
- bottom surface 16 forms a seal with flange surface 53 c .
- the bottom of the V-shaped portion 15 defines a bottom bridge which forms a hinge 17 between the inner ring projection 20 and the outer ring projection 30 , with the two legs of the V-shaped portion 15 formed by inner wall 23 of outer ring projection 20 and outer wall 33 of inner ring projection 30 .
- the combination of the resilient material comprising overcap 10 and the structure of the hinge 17 allow the inner wall 23 and the outer wall 33 of the V-shaped 15 portion to serve as arms of the hinge 17 between the outer ring projection 20 and the inner ring projection 30 , to help achieve attachment of the overcap 10 on container 50 .
- the overcap 10 contacts various surfaces of the container 50 at a number of contact points or lines.
- inwardly facing wall surface 22 contacts chime surface 52 a
- outwardly facing wall surface 32 contacts flange surface 53 a
- hinge 17 contacts flange surface 53 c .
- the multiple contact points or lines ensures there is a tight fit between the overcap 10 and the container 50 .
- a series of convex projections or raised notches 24 are formed on an inwardly facing surface of outer ring projection 20 which abut top surface 52 b of chime 52 .
- the raised notches 24 provide small vent channels to vent gas up and over chime 52 and then down along a gap formed between inwardly facing surface 22 and chime 52 .
- An annular disc portion 40 extends substantially horizontally and radially inward from the inner ring projection 30 until about midway to the center of the overcap 10 at which location a dome 42 is formed.
- the dome 42 extends inward up to a further raised center portion 46 .
- the thickness of the material forming the dome 42 is between 1 ⁇ 3 and 2 ⁇ 3 the thickness of the material forming the annular disc portion 40 , and preferably 1 ⁇ 2 as thick.
- the container 50 is shipped with dome 42 in a bowed upward convex position, as viewed looking down from above, with the center of the dome being about the same height as the top of the inner and outer ring projections 20 and 30 . This position accommodates stacking of one container on top another container when the dome is in its convex position.
- the dome 42 is transformable by pushing the dome center 46 until the dome inverts with the dome 42 substantially below the bottom of the remainder of the overcap 10 , to form an upward concave position.
- the dome 42 is inverted by a person using the thumb or palm of a single hand, and preferably in a single action, using the thumb or palm to affix and/or seal the overcap to the container while inverting the dome. Further, when the dome is inverted, the overcap 10 produces an audible noise or “snapping” sound.
- annular disc portion 40 In the inverted, concave position, the annular disc portion 40 is bent inward and downward somewhat as shown generally by broken line 42 ′ in FIGS. 3 and 4 .
- an audible noise of a “swoosh” is produced as air is displaced from inside the container to the exterior environment. The audible noise may indicate to consumers that freshness of the food product will be preserved by a tight seal and the expulsion of air from inside the container.
- the dome 42 exerts radially outward pressure or force on inner ring projection 30 and, in particular, inner wall 31 , which in turn applies a radially outward force on flange surface 53 a , thereby forming a tighter seal between the overcap 10 and the container 50 when the overcap 42 is in the concave position.
- vent channels 48 are formed on inwardly facing surface 49 of dome 42 and annular disc portion 40 , forming channels in the inwardly facing surfaces and forming a projection extending upward from the top surface of the dome 42 and annular disc portion 40 .
- the vent channels 48 extend radially from the dome center 46 along dome 42 and annular disc portion 40 , terminating between each of the circumferential disposed series of upper/lower projections 34 , 36 .
- the vent channels 48 provide a downstream venting path allowing for the release of gas pressure in the container 50 , venting gas from the container 50 to the inner ring portion 30 of the overcap 10 .
- the overcap 10 may be placed on the container in either its convex or concave position. In either case, by moving the inner ring projection 30 and outer ring projection 20 onto the chime 52 of the container, the overcap will be tightly attached to the container as described above. But preferably, the user will place the overcap 10 onto the container in the convex position so that the user can invert the cap which expels air and provides an audible snap sound which further increases the tightness of the overcap on the container and/or provides the user with the perception/assurance that the overcap is tightly attached to the container, and a “swoosh” sounds as air is expelled from inside the container. As a result, the freshness of food product inside the container 50 is preserved by removing air from inside container 50 .
- the overcap For subsequent removal of the overcap, a portion of the outer ring 20 projection is easily pulled upward off of the outer projection 52 a of the chime 52 which, in turn, moves an adjacent portion of the series of upper projections 34 and lower projections 36 up past the horizontal flange 53 .
- the overcap is sufficiently flexible so that the remainder of the overcap is then easily pulled from the container 50 .
- the series of upper and lower projections of the inner ring projection 30 straddle inwardly directed horizontal flange 53 of the container so as to effect a tight snap fit with audible indication that the overcap 10 is firmly attached to the container 50 .
- the V-shaped portion 15 serves as a hinge between the outer ring projection 20 and the inner ring projection 30 which enhances the attachment of the overcap 10 to the container 50 and in particular helps in directing the projection 36 over the flange 53 . Further, the V-shaped portion engages a top surface 53 c of the horizontal flange 53 to further effect the tightness formed between the overcap 10 and the container 50 .
- vent channels 48 located on the inward side of the dome 42 and annular disc 40 and raised projections 24 allow for gas to be vented from the inside of container 50 to the exterior environment.
- Overcap 110 has a dome 142 , a V-shaped portion forming a valley 160 and a skirt 126 .
- the dome 142 extends substantially across the diameter of the overcap 110 terminating at the valley 160 .
- Valley 160 is defined by legs 162 , 164 which form a pivotal hinge therebetween, forming the apex 166 of the valley 160 .
- overcap 110 has an invertible dome 142 which has a convex position shown in FIGS. 7 a , 8 a and a concave inverted dome position 142 ′, shown in FIGS.
- overcap 110 When the overcap 110 is in its inverted dome position 142 ′, an outward facing surface 168 of leg 162 abuts flange surface 153 a and inwardly facing overcap surface 116 abuts flange surface 153 c .
- overcap 110 does not have a series of vent channels formed on an inwardly facing surface of the dome 142 , nor does the inward facing surface of overcap 110 have a series of convex projections or raised notches, or a series of pairs of radially upward convex projections 36 to straddle flange 153 of the container 150 .
- a user To close container 150 using overcap 110 , a user first loosely places the overcap 110 over the opening of the container, as depicted in FIGS. 7 a , 8 a , while the overcap 110 is in its convex position.
- the overcap 110 When the overcap 110 is loosely placed on container 150 , as shown in FIGS. 7 a , 8 a , the skirt 126 abuts and is in contact with container rim 151 , but outward facing surface 168 of leg 162 is not in contact with flange surface 153 a nor is overcap surface 116 in contact with flange surface 153 c .
- a user applies a downward force to the top of dome 142 which pushes the overcap 110 inward towards container 150 , transforming the dome 142 from its convex position to its concave position 142 ′ depicted in FIGS. 7 b , 8 b , and thereby forcing air from inside container 150 to the exterior environment and producing a “swoosh” sound.
- Continued downward movement forces the outward facing surface 168 of leg 162 to be urged into contact with the flange surface 153 a and overcap surface 116 into contact with flange surface 153 c.
- the dome in its inverted concave position 142 ′ exerts a radially outward force on leg 162 to provide a tight seal on flange surface 153 a .
- pulling back on the skirt 126 allows one to remove overcap 110 from container 150 which preferably transforms the dome from its concave position 142 ′ to its convex position 142 .
- overcap 210 seals container 250 .
- Overcap 210 like overcaps 10 and 110 , includes an invertible dome 242 , a skirt 226 and a valley 260 formed therebetween. Like overcap 110 , overcap 210 does not have radially extending vents or notches to vent air from inside the container 250 to the exterior environment.
- the invertible dome 242 comprises a central portion of the overcap 210 , terminating at a valley 260 formed by legs 262 , 264 .
- the legs 262 , 264 are pivotally connected to each other to form a hinge at an apex 266 of the valley 260 .
- an angle formed between the legs 262 , 264 is acute and smaller than the angle formed between the legs 262 , 264 when the dome is in its concave position 242 ′, as shown in FIG. 9 e .
- overcap 210 is transformed from its convex position ( FIG. 9 d ) to its concave position 242 ′ ( FIG.
- the legs 262 , 264 pivot relative to each other so as to increase the angle formed therebetween.
- skirt 226 ′ is flared outward relative to skirt 226 when the overcap 210 is in its convex position.
- overcap 210 As with overcap 10 , 110 , applying a downward force, indicated as arrow 270 , transforms overcap 210 from its convex position ( FIG. 9 d ) to its concave position 242 ′ ( FIG. 9 e ). Further, as with overcaps 10 , 110 , to seal container 250 , the overcap 210 is first loosely placed over the opening of container 250 and subsequently pressing down on dome 242 , in a single action, produces an audible sound as the overcap 210 engages the surfaces of container 250 to seal the container 250 and an audible “swoosh” sound as air is expelled from inside the container 250 to the exterior environment. Pulling back on the skirt 226 ′ allows one to remove the overcap 210 from the container 250 which simultaneously transforms the overcap from its concave position to its convex position.
